The blind man was out walking with his seeing -eye dog when suddenly the animal paused and wet the man's leg. Bending down, the blind man stretched out his hand and patted the dog's head.

Having watched what happened, a passerby said, "Say, why are you patting him? That dog just peed on your leg!"

"I know," said the blind man, "But I gotta find his head before I can kick his butt."
